Press release issued on 23rd September, 2004
Outline of national prospecting plan for replacement resources of crisis mines (2004 ~ 20 10)
With the acceleration of industrialization and urbanization, especially after China entered the new stage of building a well-off society in an all-round way, the supply and demand pattern of major mineral resources and primary products in China has changed greatly, and the restrictive role of resources on economic development has become more and more obvious. Oil, iron, manganese, chromite, copper, bauxite, potassium salt and other major minerals related to the national economy and people's livelihood and national economic security will be in short supply for a long time.
The report of the 16th National Congress of the Communist Party of China put forward the goal of building a well-off society in an all-round way in the first 20 years of the 20th century, and the Third Plenary Session of the 16th Central Committee further explicitly adhered to the people-oriented principle, established a comprehensive, coordinated and sustainable Scientific Outlook on Development, and put forward higher requirements for the mineral resources security system. A number of large and medium-sized mining enterprises in China are facing severe situations such as resource crisis, idle production capacity, sharp drop in output and unemployment of workers, which directly affect the sustainable development of the national economy and social stability. It has become one of the hot and difficult issues to be solved urgently, and has attracted great attention from the CPC Central Committee and the State Council.
In May 2000, at the Third National Stratigraphic Conference, Comrade Wen Jiabao pointed out that it is necessary to strengthen the process of replacing resources in mines. Since the founding of New China, many important mineral resources have been discovered by geological exploration, which has played an important supporting role for the development of national economy. But now, the mine resources are exhausted and the replacement resources are insufficient, especially coal mines, non-ferrous metals and other minerals.
On June 5438+1October 65438+September, 2002, Comrade Wen Jiabao pointed out in the article "Non-ferrous metal mines are facing resource crisis, and it is urgent to strengthen mine geological work": "Strengthening geological prospecting in non-ferrous metal mines and prolonging mine life is not only an urgent task at present, but also a long-term strategic task. To carry out a new round of prospecting in nonferrous metal mines, it is necessary to formulate a general plan and determine the focus of work according to market demand; We must attach importance to comprehensive research, design and evaluation, and try our best to adopt new technologies and methods; We must demonstrate scientifically and stress economic benefits; It is necessary to give full play to the role of the existing geological team and continue to promote the reform of the geological work management system. "
On September 27th, 2002, Comrade Wen Jiabao gave instructions on "Request for Instructions on Strengthening Geological Prospecting in Nonferrous Metals Mines" submitted by the former State Economic and Trade Commission and the Ministry of Land and Resources to the State Council: "Efforts should be made to solve the problem of resource replacement in crisis mines. Through deep and peripheral exploration of large and medium-sized mines with resource conditions and market demand, the economic benefits of mines will be improved and the service life of mines will be extended. "
June 5438 +2002 10, Comrade Wen Jiabao emphasized at the 50th anniversary of the geological work in New China and the 80th anniversary of the founding of geological society of china: "With the sustained and rapid growth of China's economy, more than half of the 45 major minerals in the country have consumed more resources than the growth rate, especially in the eastern and central regions, a number of old mines that were famous in the past have dried up and become crisis mines. It is an extremely urgent task to find new replacement resources around or deep in old mines with market demand and resource potential, which has economic and social benefits. "
The exploration of replacement resources in crisis mines is a commercial geological work supported by national organizational policies. The main goal is to find and prove a batch of new resource reserves around or deep in the old mines with resource potential and market demand, and extend the service life of the mines.
The planning period of the Outline of the National Exploration Plan for Successive Resources of Crisis Mines (hereinafter referred to as the Outline) is from 2004 to 20 10. The "crisis mines" in this outline refer to large and medium-sized state-owned mines with recoverable reserves less than 5 years (severe crisis), 10 years (moderate crisis) and 15 years (light crisis) under the existing mining and utilization technology and mining capacity.
I. Basic information
(A) the status of mineral resources development in China
Since the founding of New China, after more than 50 years' efforts, China's mining industry has made great progress and established a relatively perfect mining development system. The development and utilization of mineral resources not only provide a lot of energy and raw materials for the national economic construction, but also provide an important source of fiscal revenue, solve a large number of labor employment, promote the development of regional economy, especially in minority areas and remote areas, and promote the rise and development of a large number of mining cities (towns) with mineral resources development as their pillar industries, such as Datong, Yanzhou, Pingdingshan, Anshan, Panzhihua, Baiyin, Jinchuan, Tongling, Dexing and Gejiu.
In 2003, there were 145400 mining enterprises in China, including 527 large mining enterprises and 1354 medium mining enterprises. In that year, the ore mining volume was 5.7 billion tons, and there were 9.297 million employees. The industrial output value was 597.65 billion yuan, and the sales income was 53 1.97 billion yuan. Among all kinds of mining enterprises in China, there are 65.438+00365 mines with 25 main metals such as iron, manganese, chromium, copper, aluminum, lead and zinc, tungsten, tin, molybdenum, gold and silver and rare earth, with an annual output of 463.88 million tons, achieving an industrial output value of 57.567 billion yuan and a profit of 3.57 billion yuan. There are 26,300 coal mines, with industrial output value1.781.300 million yuan and total profit 1.764 million yuan. There are 456 phosphate rocks with an annual output of 27.68 million tons, an industrial output value of 2.05 billion yuan and a total profit of 62.36 million yuan. The development and utilization of mineral resources have made great contributions to the national and local economic development.
In 2003, the national output of raw coal1600 million tons, pig iron over 200 million tons, and non-ferrous metals 10 nearly120,000 tons. The rapid economic development has driven the demand for mineral products to climb. In 2003, the import volume of mineral products increased greatly, including 91120,000 tons of crude oil, 0/48130,000 tons of iron ore, 2.86 million tons of manganese ore, 0.78 million tons of chromite, 2.67 million tons of copper ore and 0.6 million tons of copper ore. China has become a big consumer of mineral products.
(B) China mine reserves are facing a serious crisis.
A large number of large and medium-sized mines tend to be exhausted. China is rich in coal resources, but after decades or even hundreds of years of mining, the recoverable reserves of some old mines tend to be exhausted. At the same time, with the state attaching great importance to environmental protection, high-sulfur coal mines will be gradually closed, resulting in the contradiction between mine pit closure and resource replacement.
By the end of the 20th century, 38 of the 4 15 large and medium-sized mines with 25 major metals in China had been closed, accounting for 9% of the total number of large and medium-sized mines. There are 54 serious crisis mines, accounting for about13%; There are 35 mines with moderate crisis, accounting for about 8%; There are 82 mines with mild crisis, accounting for about 20%. If measures are not taken as soon as possible, it is predicted that the annual output of large and medium-sized metal mines in China will decrease by 77 million tons in the next 10 year. The problem of insufficient reserves of large and medium-sized mines in China is very serious, and it is urgent to find replacement resources.
The depletion of reserves in large and medium-sized mines directly affects the sustainable development of China's economy and society. The crisis mines in China are mainly concentrated in the old industrial bases. In these mining cities, the output value of mining and mineral products processing industry accounts for more than 30% of the city's total industrial output value, and some even reach 90%. The rise and fall of these important resource production bases determines the rise and fall of their cities, and has an impact on the regional economy and even the national economic development. At present, 22 projects 122 have been approved for the closure and bankruptcy of resource-exhausted coal mines and non-ferrous metal mines, involving about 600,000 employees and 420,000 retirees. If these "hot spots" are not properly solved, it will endanger regional economic development and social stability.
According to the survey, 47 mining cities and more than 400 mines in China will face the depletion of proven reserves, which will directly affect the work and life of more than 3 million miners and 10 million family members. For example, the mining history of Fuxin coalfield exceeds 100 years, and the remaining service life of some mines is less than one year. Fuxin Mining Group Company * * * has 6.5438+0.7 million employees. After the closure of Haizhou Open-pit Mine, nearly 1 10,000 coal miners will be unemployed, the lives of about 300,000 people will be affected, and billions of state-owned assets will be idle. Another example is Gejiu mining area in Yunnan, which is the tin capital of the world, with a total proven geological reserve of 2 million tons, ranking first in the world. After long-term large-scale mining, the service life of mine basic reserves is only 5 years. At present, Yunxi Group Company, the main production enterprise in the mining area, has a total of 5 large and medium-sized production mines 15, including 4 crisis mines15. Yunxi Group Co., Ltd. is a non-ferrous metal joint venture with 30,000 employees. It is the second largest tin producer in the world and the largest tin exporter in China, accounting for 30% and 65,438+00% in the domestic and international markets respectively. Gejiu has a population of about 200,000. If the problem of alternative resources cannot be solved as soon as possible, tens of thousands of workers will lose their jobs, which will have a great impact on the social security system in Gejiu city. Improving the level of base mine resources guarantee plays an important role in maintaining the advantages of tin resources in China and alleviating the trade pressure of some mineral products in serious shortage in China.
(c) Some mines with resource crisis have exploration potential.
The prospecting conditions in the periphery of crisis mines are favorable. Mining practice at home and abroad shows that the deep and periphery of developed mines are important ways to discover new deposits and expand resource reserves. According to statistics, since 1970s, large and super-large precious metal deposits 100 have been discovered abroad, of which at least 58% were found around the known deposits. 90% of the 39 giant porphyry copper deposits in North America are found near known mining areas. Giant copper deposits were discovered on the south and north sides of Chuchi Camata copper mine in Chile, making the copper reserves reach 58.38 million tons, making it the largest copper deposit in the world. Indonesia discovered a giant copper-gold mine in Glesburg, 3 kilometers north of the Hertzburg copper mine, adding 9.53 million tons of copper, 2/217 tons of gold and 2,062 tons of silver. The discovery of Kangjiawan large lead-zinc deposit hidden under the red bed in the periphery of Shuikoushan mining area in Hunan Province and Jinchuantang tin deposit in the periphery of Shizhuyuan world-class tungsten-tin-molybdenum-bismuth deposit indicate that there are a number of large and medium-sized deposits with prospecting potential in the periphery. In recent years, many western mining companies have adopted the exploration strategy of giving priority to prospecting in the periphery of mining areas. In contrast, many productive mines in China have not paid enough attention to the prospecting of replacement resources due to various conditions such as system, technology and capital, and there is no small prospecting space in the deep and periphery of the mining area.
There is great prospecting potential in the deep part of crisis mines. The mining depth of most mines in China is generally less than 500 meters, and there is great potential for prospecting in deep mines. The current exploration and mining technology is feasible in the depth range of 500 ~ 1000 m, and the exploration and mining depth of many large mines abroad has exceeded 1000 m. South African Rand Gold Mine has a mining depth of 4,000m, and barberton Gold Mine has reached 3,800m. The occurrence depth of Dongguashan large copper deposit in Tongling, Anhui Province is about 1000 meters. Fankou lead-zinc mine has found that the recoverable metal reserves below 500 meters exceed 1 10,000 tons; In recent years, most of the large-scale gold mines with more than 100 tons, such as Jiaodong Xincheng, Taiwanese businessmen and Fushan, have newly increased reserves in the "secondary enrichment zone" below 500 meters.
It is not uncommon to look for minerals in the periphery of crisis mines. In 1950s and 1960s, people didn't know enough about the complexity and diversity of the metallogenic system, and they didn't know much about the types of ore deposits, metallogenic series, mineralization zoning and combination, and paid attention to single prospecting. In recent years, many large and medium-sized gold and silver deposits such as Gaojiabaozi large silver mine, Xiaotongjiabaozi gold mine and Linjiasandaogou gold mine have been discovered in the periphery of Qingchengzi lead-zinc mine in Liaoning Province, making Qingchengzi area a super-large gold-silver polymetallic ore field. After the discovery of Kangjiawan concealed large lead-zinc mine in Shuikoushan mining area, Hunan Province, Longwangshan, Laoyachao, Xianrenyan and other gold mines were discovered outside the mining area. Jinshan large gold deposit and Yinshan large copper polymetallic deposit have also been found in the periphery of Dexing copper mine in Jiangxi Province.
The actual mining reserves of many metal mines in China often exceed the design reserves of mine construction. In particular, some large and medium-sized metal mines have the phenomenon of "extended service", and the average "extended service" period is 10.74 years. For example, Jiangxi Piaotang tungsten mine has a new reserve of 92,000 tons (tungsten trioxide, the same below); Hunan Yaogangxian Tungsten Mine 1955 submitted reserves of 75 19 tons, and since then, it has replenished reserves of 37,294 tons while exploring and mining; The original design production life of Xihuashan Tungsten Mine in Jiangxi Province was 15 years, with 52,668 tons of new mine exploration reserves and nearly 30 years of extended service life. The newly-increased proven reserves of Hongtoushan Copper Mine in Liaoning Province are twice as much as when the mine was built, and the mine life is extended by 25 years.

As a policy support for crisis mines, state financial investment can be converted into state capital in accordance with relevant state regulations after successful exploration; Priority is given to projects with matching funds from local governments and mining enterprises under the same conditions; Encourage mining enterprises to invest in replacing resources for prospecting, and promote mining enterprises to gradually form a virtuous circle mechanism; Geological prospecting units rely on their own advantages of having a large number of materials and talents to undertake the implementation of the project. Adhere to the combination of mining enterprises, geological prospecting units and scientific research units, give play to the role of trade associations, and improve the prospecting effect of resources crisis mines. Provincial land and resources departments and financial departments should play the role of government supervision and management, and create a good development environment.
3. Strengthen policy research to promote the revitalization of mining enterprises in resource crisis. The revitalization of crisis mines is a systematic project. Crisis mines not only need to carry out a new round of prospecting work to solve the urgent need, but also need to enhance their hematopoietic function. According to the degree of mine crisis and the types of mining cities, focusing on the relationship between mine pit closure and mining enterprise closure, the construction of "mining city" and industrial structure adjustment and transformation, we will study and formulate tax policies, industrial assistance policies, employee resettlement and re-employment policies and mine environmental governance policies and suggestions.
4. Make full use of new theories, technologies and methods to improve the prospecting effect. The deep and peripheral geological work of the mine is heavy, and the exploration depth is deep, so the exploration work is difficult. According to the specific situation of the mine, we must strengthen the comparative study and effectiveness test of new technologies and methods, strengthen positioning prediction and comprehensive exploration evaluation, shorten the prospecting period and improve the prospecting effect. Make full use of the new metallogenic theory, strengthen tackling key problems, and expand new prospecting direction and new deposit types.
